일반적으로, 가솔린, 경유, 또는 LPG를 연료로 하는 자동차는 다량의 유해 배기가스를 발생시켜 대기를 오염시킬 뿐만 아니라 지구 온난화까지 유발시켜 지구환경 뿐만 아니라 인류에 많은 피해를 발생시키고 있다. In general, car petrol, diesel or LPG as fuel is to not only generates a large amount of harmful exhaust gases pollute the atmosphere to cause global warming, as well as the global environment and caused a lot of damage to the human race. 그에 따라, 대부분의 관련업계에서는 그와 같은 문제를 해결하고자 배기가스의 발생이 현저히 낮은 하이브리드 자동차(HEV)나 배기가스의 발생이 전혀 없는 전기 자동차(EV)에 대한 연구가 활발히 진행되고 있다. Accordingly, it is being actively research on the most relevant with no generation of exhaust gases significantly lower incidence of the hybrid vehicle (HEV) or an exhaust gas-electric vehicles (EV) to solve such problems in the industry.

상기 HEV는 가솔린, 경유, 또는 LPG 등과 같은 연료를 사용하는 내연기관을 통해 주행 가능할 뿐만 아니라, 메인 전지로부터 전력변환회로를 통해 공급되는 전기를 동력원으로 하는 구동모터를 통해서도 주행 가능하며, 나아가 그 HEV는 각 주행상황에 대응하여 차량의 연비가 최대한으로 향상되도록 제어되게 되어 있다. The HEV is possible running through the driving motor as a power source for electricity, as well as possible driving through an internal combustion engine using a fuel, such as gasoline, diesel, or LPG, supplied via the power conversion circuit from the main battery, and further the HEV is to be controlled so as to improve the fuel economy of the vehicle as much as possible in correspondence to each running state.

상기 HEV의 구동모터는 차량의 제동 또는 감속시 HCU(Hybrid Control Unit)의 제어를 통해 동력모드에서 발전모드로 전환되게 되며, 이때 상기 메인 전지는 상기 HCU와 접속된 배터리제어부(BMS; Battery Management System)의 제어를 통해 발전기(또는 구동모터)로부터 발생되는 전기에너지에 의해 그때그때 마다 충전될 수 있게 된다. The drive motor of the HEV is to be switched to the power mode from the power mode through the control of the braking or deceleration of the vehicle HCU (Hybrid Control Unit), wherein the main battery is a battery control unit (BMS connected to the HCU; Battery Management System ) per time to time by the electric energy generated from the generator (or a drive motor) under the control of it it is possible to be filled. 이때, 상기 발전기로부터 메인 전지로 인가되는 전류는 차량의 주행상황에 따라 다르고 불연속적이다. At this time, the current applied to the main battery from the alternator is discontinuously varied depending on the running conditions of the vehicle.

한편, 상기 구동모터를 위한 전력변환회로와 메인 전지 사이에는 도 1에 도시된 바와 같이, 전지팩연결회로(1)가 구비되며, 이 전지팩연결회로는 발전모드시 상기 구동모터(또는 발전기)로부터 메인 전지로 충전전류를 인가하고, 구동모드시 상기 메인 전지로부터 구동모터로 구동전류를 인가하며, 그에 따라 차량은 전기에너지에 의해 구동될 수 있게 된다. On the other hand, as shown in Figure 1 between the power conversion circuit and the main battery for the drive motor, the battery pack connection circuit (1) are provided, the battery pack connection circuit is the drive motor (or generator) during generating mode applying a charge current from the main battery, and, and applying a drive current to the drive motor from the main battery when the drive mode, whereby the vehicle is able to be driven by the electrical energy.

여기에서, 상기 전지팩연결회로(1)에는 메인 전지로부터 전력변환회로로 전류를 인가하는 HV(-)도선과 HV(+)도선이 각각 일정패턴으로 배선되어 있다. Here, the battery pack connection circuit 1 is provided for applying a current to the HV power conversion circuit from the main battery (-) have conductors and HV (+) conductors are routed to the respective predetermined pattern. 상기 HV(+)도선의 입력단쪽에는 차량의 시동키의 온시 메인전지로부터 전력변환회로로 인가되는 서지성 과전류를 제한하는 프리차지 저항(Pre-charge Resistor)(2)이 연결되어 있다. The HV (+) input terminal side of the wire is pre-charging resistor (Pre-charge Resistor) (2) is connected to limit the standing intelligence over current that is applied to the power conversion circuit from the main battery turns on the ignition key of the vehicle. 또한, 상기 프리차지 저항과 출력단 사이에는 과전류의 흐름을 단속 가능하게 하는 고전압 프리차지 릴레이(Pre-charge Resistor)(3)와 고전압 주전원용 릴레이(4)가 각각 다른 경로를 통해 연결되어 있다. In addition, the pre-charge the high-voltage resistance and a precharge relay between output terminal to enable the intermittent flow of the overcurrent (Pre-charge Resistor) (3) and the main high-voltage power supply relays (4) are each connected via a different route. 한편, 상기 HV(-)도선에는 메인 전지로부터 구동모터로 인가되는 과전류의 흐름을 단속 가능하게 하는 다른 주전원용 릴레이(4a)가 구비되어 있다. On the other hand, the HV (-) lead is provided with a different state relay for power (4a) for enabling intermittent flow of over-current is applied to the drive motor from the main battery.

However, the battery pack of a conventional hybrid vehicle and an electric vehicle connected to the circuitry warning means do not have consuming the battery pack connection circuit high voltage pre-charge over-current flow or in the resistance over-voltage of, even when in the precharge relay ON-state driver were not appropriately cope with such an emergency situation, yet there is a problem that causes the over-current to the drive motor-side power converter of the vehicle flows to damage the smoothing capacitor.

전술한 바와 같이 구성된 HEV와 EV를 위한 전지팩 관리방법을 도 3을 참조하여 설명하면 다음과 같다. Referring to Figure 3 a battery pack management method for HEV and EV configured as described above as follows.

먼저, 차량의 시동키가 온상태로 전환되면 배터리제어부(BMS) 또는 차량제어장치를 통해 전지팩연결회로(1)의 해당 릴레이(3,4,4a)에 제어신호용 전원을 인가한다(S300). First, when the ignition key of the vehicle is turned on the battery controller control signal to the power relay (3,4,4a) of the battery pack connection circuit 1 via the (BMS) or vehicle control unit (S300) .

이어서, 상기 전지팩연결회로(1)의 프리차지 저항(2)으로부터 전류 또는 전압을 검출한다(S305). Then, the detected current or voltage from a pre-charging resistor (2) in the battery pack connection circuit (1) (S305).

이어서, 상기 검출된 전류 또는 전압을 배터리제어부(BMS)의 메모리부(도시되지 않음)에 미리 저장된 표준대응정보와 비교한다(S310). Then, comparing the detected current or voltage with standard correspondence information pre-stored in the memory unit (not shown) of the battery control unit (BMS) (S310). 그런 다음, 그 검출된 값이 해당 전지팩의 정상범위 내에 속하는지의 여부를 판단한다(S315). Then the following, the detected value, it is determined whether or not fall within the normal range of the battery pack (S315).

상기 판단결과, 그 검출된 값이 정상범위 내에 있으면 정상적인 충전작업을 수행하고(S325), 그렇지 않으면 상기 프리차지 릴레이(3)를 오프시킨 후(S335) 상기 배터리제어부와 전기적으로 연결되는 경고수단(도시되지 않음)을 통해 운전자에게 경고신호를 보낸다(S350).

Wherein when the pre-charge relay 3 is turned off the precharge is to be the relay is over-current or over-voltage is applied toward the motor unit of the vehicle off from, and thus the smoothing capacitor in the motor unit is able to be protected from over-current or over-voltage .

한편, 상기 경고수단은 표시램프 또는 스피커일 수 있으며, 상기 표시램프는 차량의 대시보드패널쪽 계기판에 구비되는 것이 바람직하다. On the other hand, the warning means preferably may be a display lamp or speaker, and the display lamp is provided in the dashboard panel, the instrument panel side of a vehicle.

이어서, 상기 프리차지 릴레이가 오프되면 그 프리차지 릴레이(3)의 오프횟수를 메모리부에 누적시킨다(S340). Subsequently, if the precharge relay is turned off the pre-charging thereby the number of times off the relay (3) accumulated in the memory unit (S340).

이어서, 상기 프리차지 릴레이(3)의 누적 오프횟수가 메모리부에 미리 저장 되어 설정된 그 프리차지 릴레이의 허용 오프횟수 이내인지의 여부를 판단한다(S345). Then, the cumulative number of times off of the precharge relay (3), it is determined whether or not the pre-stored in the memory unit within the allowed off number of times of the pre-charge relay is set (S345).

상기 판단결과, 상기 누적된 오프횟수가 허용 오프횟수 이내이면 경고수단을 통해 운전자에게 경고신호를 보낸다(S350). A result of the determination, when the accumulated off number of times within the allowed off number of times that sending a warning signal to the driver through the warning means (S350). 한편, 그와는 달리 상기 누적된 오프횟수가 허용 오프횟수를 초과하면 전지팩의 운용을 차단한다(S355). On the other hand, in contrast to that it is the accumulated off number of times exceeds the allowed off number of times when block the operation of the battery pack (S355).

전술한 바와 같이, 본 발명은 차량의 시동키의 온시 전지팩으로부터 차량의 모니터유니트쪽 전력변환회로로 서지(Surge)성 전류가 인가되었을 때 그 전력변환회로와 전지팩 사이에 배치되는 전지팩연결회로를 통해 전력변환회로의 평활캐패시터 또는 관련 소자들의 손상 가능성을 미리 차단할 수 있게 한다.
